An alternative definition of the quantum microcanonical ensemble
Year: 2006
Type: preprint
Abstract: We discuss an alternative definition of the quantum microcanonical ensemble, in which statistical averages are obtained by a combination of a time average and a maximum entropy argument to resolve the lack of knowledge about initial conditions. As a result, statistical averages of linear observables coincide with values obtained in the canonical ensemble. Non-canonical averages can be obtained by taking into account conserved quantities which are non-linear functions of the microstate.
